Are these models using different logins and schemas? If not, they should all share the same connection if their connection dictionaries are .equals(). If they are all different, then EOF is going to want to consider them to be different. Putting the schema name in the table name and ensuring that the connection dictionaries are .equals() may work, I have never tried that.
